Meller Optics, Inc.

The sapphire is available in all material grades, from mechanical nonoptical to defect-free optical and wavelength transmission products in all orientations with no lattice distortion. It is available as blocks, lenses, carriers, wafers, windows and domes in a variety of configurations and sizes from 0.5- to 5-in. optical density, ±0.00025 in.

Featuring Moh 9 hardness, the sapphire can be finished to 1/10-per-wave flatness per inch, parallelism to 2 arcsec and surface finishes to 10-5 scratch-dig per MIL-PRF-13830, depending upon material and configuration. Lenses are available planoconvex and concave, biconvex and concave, and meniscus; windows and substrates can be plane, wedged and tapered.
